Cost-Effective Authentic and Anonymous Data Sharing with Forward
Security
Abstract:
Data sharing has never been easier with the advances of cloud computing,
and an accurate analysis on the shared data provides an array of benefits to both the
society and individuals. Data sharing with a large number of participants must take
into account several issues, including efficiency, data integrity and privacy of data
owner. Ring signature is a promising candidate to construct an anonymous and
authentic data sharing system. It allows a data owner to anonymously authenticate
his data which can be put into the cloud for storage or analysis purpose. Yet the
costly certificate verification in the traditional public key infrastructure (PKI)
setting becomes a bottleneck for this solution to be scalable. Identity-based (IDbased) ring signature, which eliminates the process of certificate verification, can
be used instead. In this paper, we further enhance the security of ID-based ring
signature by providing forward security: If a secret key of any user has been
compromised, all previous generated signatures that include this user still remain
valid. This property is especially important to any large scale data sharing system,
as it is impossible to ask all data owners to re authenticate their data even if a
secret key of one single user has been compromised.

Existing System:
Considering energy usage data sharing in Smart Grid as an example, there are
several security goals a practical system must meet, including:
Data Authenticity:
In the situation of smart grid, the statistic energy usage data would be
misleading if it is forged by adversaries. While this issue alone can be solved using
well established cryptographic tools (e.g., message authentication code or digital
signatures), one may encounter additional difficulties when other issues are taken
into account, such as anonymity and efficiency;
Anonymity:
Energy usage data contains vast information of consumers, from which one
can extract the number of persons in the home, the types of electric utilities used in
a specific time period, etc. Thus, it is critical to protect the anonymity of
consumers in such applications, and any failures to do so may lead to the
reluctance from the consumers to share data with others; and
Efficiency:

DEVELOPMENTS
The number of users in a data sharing system could be HUGE (imagine a
computation and communication cost as much as possible. Otherwise it would lead

Proposed System:
Our system proposes a new notion called forward secure ID-based ring
signature, which is an essential tool for building cost-effective authentic and
anonymous data sharing system:

For the first time, we provide formal definitions on forward secure ID-based ring
signatures;
Present a concrete design of forward secure ID based ring signature. No previous
ID-based ring signature schemes in the literature have the property of forward
security, and we are the first to provide this feature;
Prove the security of the proposed scheme in the random oracle model, under the
standard RSA assumption; and
1) It is in ID-based setting. The elimination of the costly certificate
environment.
2) The size of a secret key is just one integer.
3) Key update process only requires an exponentiation.
4) We do not require any pairing in any stage.
Advantages:

